Exodus 38:16 (KJV)

The hangings of the one side of the gate were fifteen cubits; their pillars three, and their sockets three.

And for the other side of the court gate, on this hand and that hand, were hangings of fifteen cubits; their pillars three, and their sockets three.

All the hangings of the court round about were of fine twined linen.

And the sockets for the pillars were of brass; the hooks of the pillars and their fillets of silver; and the overlaying of their chapiters of silver; and all the pillars of the court were filleted with silver.

And the hanging for the gate of the court was needlework, of blue, and purple, and scarlet, and fine twined linen: and twenty cubits was the length, and the height in the breadth was five cubits, answerable to the hangings of the court.
